1. Go to a regular store to buy stationery products produced by regular manufacturers. Generally, regular supermarkets or franchise stores will choose regular channels for purchase.
2. Try not to buy rubbers with cute shapes and fragrances as their selling points. Often, the more complex the process, the more chemicals are added.
3. When purchasing, you must read the product identification: factory name, place of origin, implementation standard (QB-2655-2004), production date.
4. Take a look at the instructions and detailed formula instructions, and buy rubbers that are labeled as free of phthalates.
5. The erasers of some well-known stationery brands are relatively safer.
